A solid conducting sphere of radius ra is placed concentrically inside a conducting spherical shell of inner radius rb1 and outer radius rb2. The inner sphere carries a charge Q while the outer sphere does not carry any net charge. The potential for rb1 < r < rb2 is:________

Answer:

The right answer is "
(KQ)/(r_b_2)".

Step-by-step explanation:

As the outer spherical shell is conducting, so there is no electric field in side from


r_b_1 < r < r_b_2.

So the electric potential at all points inside the conducting shell that from


r_b_1<r<r_b_2

and will be similar as well as equivalent to the potential on the outer surface of the shell that will be:


v=(KQ)/(r_b_2)

Thus the above is the right solution.
